Adobe Photoshop, otherwise known as Photoshop, is an image editing software created by Adobe Systems devoted to photo/image editing and effect creation. The software is widely used by digital photographers and advertising companies to be considered a market leader for image/photo processing software, and, with Adobe Acrobat, is considered the best product ever produced by Adobe Systems.
The eighth version of the application is called Photoshop CS (Creative Suite), version nine is called Adobe Photoshop CS2, version ten is called Adobe Photoshop CS3, the eleventh version is Adobe Photoshop CS4, the twelfth version is Adobe Photoshop CS5, the thirteenth version is CS6, and the most recent version is Adobe Photoshop CC (Creative Cloud).
Photoshop is available for Microsoft Windows, Mac OS X, and Mac OS; version 9 and above can also be used by other operating systems like Linux with the help of certain software such as CrossOver.
In 1987, Thomas Knoll, a PhD student at the University of Michigan, wrote a program on his Macintosh Plus to display grayscale images against monochrome screens.
The program, called Display, caught the attention of his brother John Knoll, an employee at Industrial Light &Magic, who advised Thomas to turn his program into a full image editing program.
Thomas took a six-month break from studying in 1988 to collaborate with his brother on the program, which has been renamed ImagePro.
After that year, Thomas made a change of his program name to Photoshop and worked in the short term with scanner manufacturer Barneyscan to distribute copies coming from subsequent programs with slide scanners; "a total of approximately 200 copies of Photoshop have been submitted" with this step.
During that fitting, John traveled to Silicon Valley in California and added a demonstration of the program to engineers at Apple Computer Inc. and Russell Brown, art director at Adobe. Both demonstrations were successful, and Adobe decided to spend a license to distribute against september 1988.
While John worked on plug-ins in California, Thomas was always in Ann Arbor to write program code. Photoshop 1.0 released against 1990 specific for Macintosh
Although photoshop is designed to edit images for paper-based prints, photoshop fitting can also be used to process images for the World Wide Web. Some recent versions also include an additional application, Adobe ImageReady, for that purpose.
Photoshop also has a close relationship with some of Adobe's other media editing, animation, and authoring software. Photoshop's original format file, .
PSD, can be exported to and from Adobe ImageReady. Adobe Illustrator, Adobe Premiere Pro, After Effects and Adobe Encore DVD to create professional DVDs, prepare non-linear image editing and special effect services such as backgrounds, textures, etc. for the benefit of television, movies, and web sites.
For example, Photoshop CS can be used to create DVD menus and buttons.
Photoshop can accept the use of several color models:
RGB color model
Lab color model
CMYK color model
The version released against 2005, is version 9. The program is marketed under the name "Photoshop CS2." "CS" reflects the integration of Photoshop products with Adobe's "Creative Suite" application called "2" as it is the second release version since Adobe integrates both products.
There are some additional against Photoshop CS2 like multiple layer selecting and "warp," curved versions derived from the transform tool and color replacement tool, which previously came as an 8BF plug-in.
For photography enthusiasts, Adobe has a "reduce grain" filter that can support optimizing confiscated photos against low-light conditions. To "clarify" the difference between CS products and previous Photoshop products, Adobe removed the Photshop eye symbol, which was presented in different forms from version 3 to version 7. Photshop CS and CS2 now make use of fur as an icon and form of identification.
A beta version of Photoshop CS3 was released for CS2 users on December 15, 2006. Unlike Photoshop CS and CS2 which make use of feathers as their logos, the logo for this third edition is typography, with the letter 'Ps' in white and a blue-gradient background.
Camera RAW 3.x
The final version comes with Adobe Camera RAW, a plugin developed by Thomas Knoll that can read some RAW file formats from digital cameras and import them directly into Photoshop.
An early version of raw plugin is also available for Photoshop 7.0.1 with an additional cost of $99 USD.
Photoshop is an industry standard image editing program intended for graphic raster professionals, the price offered is also high; approximately US$600.
This situation provoked some programmers to design graphics tools at a more affordable price. To face this competition, and to deal with piracy of its products, Adobe introduced Photoshop Elements, another version derived from a more minimalist Photoshop, at an affordable price; under US$100. This product is intended for home users and eliminates some professional features.
